  1. I still wish someone would re-package the VBXE hardware into something that could plug into the empty slots of an Incognito-equipped 800.
  2. A VBXE-equipped Atari beats the hell out of whatever an XEP80 was capable of in the first place. Why go backwards?
  3. I typically have 8 APT partitions starting at D5:, on the off chance I get the urge to do something stupid like mount 3 or 4 ATRs in the Loader at the time, or move a bunch of random stuff off ATRs via RespeQt, FujiNet or my SDrive-MAX to my APT partition(s).
  4. Apologies if I've missed it, but does this machine have an Ultimate 1MB installed? If so, you might consider installing a small 100pF capacitor between the RESET and GROUND pins on the U1MB board itself. I started having similar configuration resets of my U1MB on a 1200XL, and it was suggested to me by @tf_hh to mod my U1MB with a capacitor like that my my problems went away. I'm pretty sure @flashjazzcat has suggested a similar mod to others in the past as well.
  5. I've built over 100 of these and never, ever run into a bad stick. Do you have a copy of Pete's Test Cartridge or the PAM SALT (diagnostic) cartridge? There are three possible problems that cause what you're seeing. 1) Marginal or bad solder joints on the (very!) small pads for the 0.1 uF capacitors that serve to effectively "amplify" the apparent range of the modern stick to meet what the 5200 POKEY circuit expects. If those caps aren't properly soldered, the stick won't register properly. 2) The POKEY Adjust resistor on your 5200 has drifted out of spec over time - this is more common than most people realize with machines pushing 38 years old. You do have to open the console to adjust it, but it's a very minor thing, much like adjusting the color potentiometer. You really shouldn't adjust it though without a way to measure the effects of your change, so if you have Pete's Test Cart or the PAM SALT cart, you should use them when making any adjustment, otherwise you're flying blind. 3) The digital pot chip might be out of spec - we ran into a surprisingly high percentage of these that would read low on one or both axis measurements and had to be replaced.
  6. Well, has anyone reached out to @Albert or another forum moderator to ask about it? That’s probably the next step.
  7. This is really off-topic since it's not hardware-related, but there's this thread stickied to the top of the forum. Of course it's 75 pages long now. It would be much more useful if it was just a single stickied post that is updated once a month or whenever someone has a change to report. https://atariage.com/forums/topic/174831-atari-8-bit-related-bbss/
  8. FujiNet is a not a telephone interface - you can only access sites on the internet, emulating Telnet-style BBS’es. So even though you’re typing “ATDT” or whatever to start the connection, the “phone number” is really an IP address or internet URL for the BBS.
  9. It's literally a physical relay that connects the RF signal from the Atari when power is applied, and otherwise allows the RF passthrough from whatever else is connected to the switchbox.
  10. Considering a simple LED can draw in the range of 20mA, that's really goddamned impressive for the Nano.
  11. Make sure you have the PBI BIOS Hard Disk enabled. EDIT: Nevermind - they wouldn't even be listed if you didn't already do that. Hmm ...
  12. Probably related to the DOS you’re using. Stock Atari DOS 2.5, for instance, only allows access to D1: and D2:. If you want to access D3: or higher, you need to run SETUP.COM, then write the new (modified) DOS files back to your boot disk. This is because each drive you enable eats up some useable RAM from the system. In an era when most Atari computers had only 48K at most, no bankswitched extra memory, and disk drives costs hundreds of 1980’s dollars each, it made no sense to expect the average user to need access to 3 or 4 drives by default.
  13. Do any of those issues cover the general issue I mentioned that, on version 1.1 with the power switch OFF, SIO passthrough doesn't seem to work?
  14. Gotta say, the combination of cartridge emulation, mounted ATRs and APT partitions all accessible under SDX is the bee's knees.
  15. My 1200XL U1MB and SIDE3 have been successfully and happily updated. Wonderful news this Saturday afternoon.
